摘要
针对宽沟煤矿发生的冲击地压,基于现场监测数据和数值模拟结果,对现场出现的多个冲击地压案例进行了分析,得出了宽沟煤矿存在两种典型的冲击地压类型:工作面坚硬顶板悬顶型冲击地压和巷道应力叠加型冲击地压。对不同类型冲击地压,采取了有针对性的防治措施。现场应用表明,冲击地压防治效果良好。
Aiming at the rock burst occurrences at Kuangou coalmine, analyzing the multiple rock burst cases appear on the on-site, which based on the on-site monitoring data and numerical simulation results. It concluded that two typical types of rock burst existed in Kuangou coalmine： working face tight roof suspension type rock burst and roadway stress superposition type rock burst. For different types of rock burst, targeted prevention and control measures are adopted. Field application shows that the control effect of rock burst is good.
